Abstract: An air cooling system for a temperature-controlled display case includes at least two modular cooling elements, one or more fans configured to provide an air flow to the at least two modular cooling elements, and an air plenum common to each of the one or more fans and the at least two modular cooling elements, the air plenum being configured to direct the air flow from the one or more fans through the at least two modular cooling elements and into a product area of the temperature-controlled display case.

Abstract: A refrigeration system for a temperature-controlled storage device includes a refrigeration circuit, a cooling circuit, and a controller. The refrigeration circuit includes a compressor driven by a brushless DC motor operable at multiple different speeds, a first heat exchanger, an expansion device, and a cooling unit in fluid communication via a first working fluid. The cooling circuit includes a pump and a second heat exchanger in fluid communication with the first heat exchanger via a second working fluid such that the first heat exchanger is liquid-cooled by the second working fluid. The controller operates the brushless DC motor at multiple different speeds to accommodate multiple different thermal loads experienced by the refrigeration system. Each of the speeds corresponds to a different thermal load. The controller modulates the speed of the brushless DC motor to maintain a desired temperature of a temperature-controlled space within the temperature-controlled device.

Abstract: A display device is disclosed for at least one food-grade object and includes a display surface to display the food-grade object, at least one passage adapted for distributing a fluid within the display device, and an ozonated water source in communication with the passage. A system is also disclosed for cleaning and moisturizing a food item in a display device and includes a fluid distribution system to distribute a fluid in relation to the display device, an ozone source in communication with the fluid to selectively provide an ozonated fluid, an application device engaging the fluid distribution system to apply the ozonated fluid in communication with the food item.

Abstract: A distributed refrigeration system has a temperature controlled case configured to store and display objects in a facility, a first coolant adapted to cool the objects and circulate through a first cooling system configured to operate with the case, and a second cooling system communicating with the first cooling system to receive a second coolant for removing heat from the first coolant. A method of providing a distributed refrigeration system for delivery to a facility includes providing a temperature-controlled case to store and display objects within a facility, assembling a self-contained first cooling system with the case to circulate a first coolant to cool the objects, and providing a second cooling system communicating with the first cooling system, the second cooling system having a supply connection and a return connection to circulate a second coolant to remove heat from the first coolant.
